A combination of
Ramp To
,
Jump To
and
Ignore
responses can be used to create an application
specific output profile.
1.6.5. X-Axis, Time Response
As mentioned in Section 1.6, a Lookup Table can also be used to get a custom output response
where the
X-Axis Type
is a
‘Time Response.’
When this is selected, the X-Axis now represents time,
in units of milliseconds, while the Y-Axis still represents the output of the function block. There is
also another setpoint associated to the Lookup Table when configured to
Time Response
which is
the
Table Auto-Cycle
setpoint.
In this case, the
X-Axis Source
is treated as a digital input. When the control input is ON, the output
will be changed over a period of time based on the profile in the Lookup Table. There are two different
scenarios on how the Lookup Table will react once the profile is finished. The first option is when
30z2h
Table Auto-Cycle
is set to
FALSE
in which case, once the profile has finished (i.e. index 10,
or
Ignored
response), the output will remain at the last output at the end of the profile until the control
input turns OFF. The second option is when 30z2h
Table Auto-Cycle
is set to
TRUE
in which case,
once the profile has finished (i.e. index 10, or
Ignored
response), the Lookup Table will automatically
return to the 1
st
response and will continually be auto-cycling for as long as the input remains in the
ON state.
When the control input is OFF, the output is always at zero. When the input comes ON, the profile
ALWAYS starts at position (X
0
, Y
0
) which is 0 output for 0ms.
In a time response, the interval time between each point on the X-axis can be set anywhere from
1ms to 1min. [60,000 ms]
